i feel weird (diffrent) around my boyfriend

It can be difficult to regain intimacy after not being together a lot. Was there a special reason you were apart (e. g. you had a demanding summer job, or he was away traveling or something)?

If you were apart because neither of you made the effort to connect, then that's something else entirely, yes?

By the way, it's okay to lose interest in someone, and call it quits when a relationship runs out of steam. There is no shame in letting it go, and not every relationship ends with a big fight, a bang. Some of them end with a whimper.

It's dating, not a marriage. That makes it easier to walk away.

meh...

my take on it is you can't feel the same way, let alone the exact same way about any person over an extended period of time.

Neither one of you remains stagnant. Relationships involve a somewhat frequent reassessment and fine tuning of our views and perspective of the other.

If you love running, do you expect to feel the exact same way about running the exact same distance on the exact same days of the week forever? or do you sometimes take a break and do something else for a while, or do your running differently? Same thing applies to eveything in your life, your eating, job, feelings toward travel, energy levels, feelings towards spritual matters, etc. Why would your feelings toward someone who is going through their own journey stay exactly the same, when you are on your own journey?

To this day, sometimes I look at the person I've been married to for 20 years and think "Who IS this person? At times I've thought "I don't know you at all" Then I access if this is a sign I need to get to know this person and who they are now.

Of course you feel differently about someone after 2 years. I'd be concerned if I didn't.

People change; time will do that to couples.

It's sad, but learning this is part of "growing up". Adults know it can't be Christmas or your birthday or vacation every day.
